Hollow metal doors are one of the most common types of doors used in commercial and industrial environments. A hollow metal door is composed of a steel frame that has steel panels laminated to both sides. Hollow metal doors are often supplied with a hollow metal frame, together creating a fire-rated assembly.
Likewise, people ask, what are hollow metal doors made of?
Hollow Metal Doors are made of channel reinforced steel sheets and filled with insulation materials such as polystyrene, kraft honeycomb or polyurethane. Standard metal doors are 1-3/4″ thick and are prime coat painted.
Similarly one may ask, what is inside a steel door?
Steel doors are comprised of either a polyurethane or polystyrene core with a steel skin over the top. A solid steel door would be prohibitively heavy and would most likely tear out the hinges. Steel between 16 and 24 gauge is used for the skin of the door.

- Add Foam Insulation Sheet. Glue a 1 to 2 inch sheet of foam insulation to the back of the door.
